Product Description
The EVQ3428A-L-00A Evaluation Board is designed to demonstrate the performances of MPS’ MPQ3428A, which has excellent protection and can provide load with12V/2A power from typical 3.3V input.
The MPQ3428A is a 600 kHz fixed frequency, high efficiency, wide input range, current mode boost converter with optional internal or external current sensing configuration for high integration and high power application. It features internally a 10mΩ, 24V power switch and a synchronous gate driver for high conversion efficiency. The MPQ3428A is available in a low profile 22-pin 3mmx4mm QFN package.
This board is configured for 12V application, the maximum output current is determined by current limit, permitted temperature rising and input voltage.

19A, 600kHz, 20V Wide Input Range, Synchronous Boost Converter with Input Disconnect Function, AEC-Q100 Qualified
The MPQ3428A is a 600kHz, fixed-frequency, high-efficiency, wide input range, current mode boost converter with optional input disconnect and an input average current limit function. The input disconnect feature provides additional protection by isolating the input from the output during output short or shutdown. For batteryoperated applications, this feature also helps prevent battery depletion.
With a programmable input average current limit, the MPQ3428A supports a wide range of applications, including POS, Thunderbolt, Bluetooth audio, power banks, and fuel cells.
The MPQ3428A features a 18mΩ, 24V power switch and a synchronous gate driver for high efficiency. An external compensation pin allows flexibility in setting loop dynamics and obtaining optimal transient performance under all conditions. The MPQ3428A includes under-voltage lockout, switching current limiting, and thermal shutdown to prevent damage in the event of an output overload. The MPQ3428A is available in a low-profile QFN-22 (3mmx4mm) package.
